PYGLET – Drawing Rectangle
  • Last Updated : 23 Sep, 2020

In this article we will see how we can draw rectangle on window in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). A rectangle is a four-sided shape where every angle is a right angle (90°). Also opposite sides are parallel and of equal length. Rectangle is drawn with the help of shapes module in pyglet.

We can create a window with the help of command given below

# creating a window
window = pyglet.window.Window(width, height, title)

In order to create window we use Rectangle method with pyglet.shapes

Syntax : shapes.Rectangle(x, y, width, height, color=(255, 255, 255), batch=None)

Argument : It takes position i.e pair of integer, width and height of rectangle, color of rectangle and last is batch object



Return : It returns Line object

Below is the implementation

code

# importing pyglet module 
import pyglet
  
# importing shapes from the pyglet
from pyglet import shapes
  
# width of window 
width = 500
    
# height of window 
height = 500
    
# caption i.e title of the window 
title = "Geeksforgeeks"
    
# creating a window 
window = pyglet.window.Window(width, height, title) 
  
# creating a batch obect
batch = pyglet.graphics.Batch()
  
  
# properties of rectangle
# co-ordinates of rectangle
co_x = 150
co_y = 150
  
# width of rectangle
width = 300
  
# height of rectangle
height = 200
  
# color = green
color = (50, 225, 30)
  
# creating a rectangle
rec1 = shapes.Rectangle(co_x, co_y, width, height, color = color, batch = batch)
  
# changing opacity of the rect1
# opacity is visibility (0 = invisible, 255 means visible)
rec1.opacity = 250
  
  
# creating another rectangle with properties
# x, y co ordinate : 50, 250
# width, height of rectangle : 300, 200
# color = red
color = (255, 25, 25)
  
# creating rectangle
rec2 = shapes.Rectangle(50, 250, 300, 200, color = color, batch = batch)
  
# changing opacity of the rec2
# opacity is visibility (0 = invisible, 255 means visible)
rec2.opacity = 100
  
  
# window draw event to draw rectangles
@window.event
def on_draw():
      
    # clear the window
    window.clear()
      
    # draw the batch
    batch.draw()
  
# run the pyglet application
pyglet.app.run()
